CARL HENRY WEISS, OF QUINCY, ILLINOIS.

PIPE STEM.

Application filed December 24, 1923.

To all whom it may concern:

Be it known that I, CARL HENRY \Vnrss, a

I citizen of the United States, and a resident of Quincy, in the countyof Adams and State of Illinois, have invented a new and usefulImprovement in Pipe Stems, of which the following is a full, clear, andexact description.

My invention relates'to improvements in pipe stems, more particularly inthe end of the stem or hit portion, and it consists in the combinations,constructions, and arrangements herein described and claimed.

An object of my invention is to provide a device which will permit afree draft, but which will prevent the concentration of a stream ofsmoke upon the tongue, thereby obviating the burning effect which ispresent in pipes having a straight bore.

A further object of my invention is to provide a pipe stem which, whilehaving a free draft, will prevent the saliva from entering the stem andinterfering with the proper operation of the pipe.

A further object of ,my invention is to provide a device of the typedescribed, in which the end of the stem has a passage extending upwardlyand thence downwardly, and terminating at a slot, beneath which is aspreader device by means of which the smoke is spread before it emerges,and which is therefore cooled in the spreading operation.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawings, forming partof this application, in which- Figure 1 is a side view of a pipeconstructed according to my invention,

Figure 2 is a sectional view of a portion of the pipe stem, showing thecourse of the bores which permit the smoke to be drawn through the stem,

Figure 3 is an enlarged section showing the manner in which the boresmay be made, and

Figure 4: is an end View of the stem.

In carrying out my invention, I may make use of a stem portion 1 of anysuitable material, having a central bore 2, and being provided with areduced threaded portion?) at one end for connection to the portion 4 ofthe pipe bowl 5. Communicating with the Serial No. 682,462.

bore 2 is a bore 6 which, as will be seen from Figure 2, extendsupwardly. The bore 6 communicates with the bore 7 which extendsdownwardly and forwardly, and terminates at a slot 8. The upper surfaceof the portion 9 is flat, as will be seen from the drawings, while thelower portion is preferably curved, as shown at 10, to conform to thecontour of the tongue. At 11, I have shown a groove which extends acrossthe top of the bit and which provides means for holding the stem firmlyin the mouth, since it permits the teeth to get a good grip on the stem.

The portion 12 at the end of the curved lower portion 10 forms also ameans which will abut the lower teeth, thus further insuring a good gripon the stem.

From the foregoing description of the various parts of the device, theoperation thereof may be readily understood. In preparing the stem, thecentral bore 2 may be made in the usual manner, and then a straight bore6 may be run from the forward end of the bit to connect with the bore 2,

as shown in Figure 3. The bore 7 may then berun from the same place, i.e., at the forward end of the bore 6, until it intersects with the slot8. The intersection of the bores 6 and 7 may then be closed, as by aplug 13. This then provides a passage for the smoke from the bowlthrough the bore 2, upwardly through the bore 6, and downwardly andforwardly through the bore 7. When the smoke hits the upper flat surfaceof the portion 9, the stream of smoke is spread out and emerges from theslot 8 at the front and at the sides thereof, so that when the smoke isdrawn into the mouth, it is partially cooled by its projection into themember 9. Furthermore, the concentrated stream of smoke is diffused, sothat with apipe using this stem end of bit there is no danger of burningthe tongue.

A further advantage, however, which the construction gives is that itwill prevent the saliva from flowing into the pipe stem, for it will beobserved that the bore 7 extends upwardly and forwardly until itcommuni- ,cates with the bore 6. Even though the pipe wire or othercleaning device to be thrust through the passages 6 and 7, after whichthe plug may be replaced.

It Will be understood that this stem may be made of any suitablematerial, and while I have shown a. threaded connection to the majorpipe portion, it might be connected in any suitable manner, withoutdeparting from the spirit and the scope of the invention.

I claim:

1. In a pipe, a stem having a longitudinal bore, a bit portion inte ralwith said stem, said bit portion having a slot extending inwardly fromthe end thereof, a smoke passage extending upwardly from said slot, andthence downwardly, and communicating with the bore, the portionunderneath the slot constituting a protecting shield for the tongue ofthe smoker.

2. In a pipe, a stem having a longitudinal bore, a bit portion integralwith said stem, a tongue shield carried by said bit portion and a smokepassage extending from said longitudinal bore upwardly into said bitportion, and thence downwardly so as to direct the stream of smokeagainst said shield.

8. In pipe, a stem having a longitudinal bore, a bit portion integralwith said stem, a tongue shield carried by said bit portion and a smokepassage extending from said longitudinal bore upwardly into said bitportion, and thence downwardly and rearwardly so as to direct the streamof smoke against said shield.
